((Warning: This will get very offensive... Don't read if your a butt hurt weaboo.))
Ok, so You guys may be thinking THIS ISN'T A CLICHE!!! Well guess what, IT IS A CLICHE!!!
People make they're characters weaboos and it makes me cringe.

Now in case you've been living under a fucking rock your whole life a weaboo is basically this:

Weaboo one: OMFG L-kun!
WTF! U don't like AOT? RU even Japanese bru? How dere u even call urslf an anime fan!!!

Weaboo two: SENPAI NOTICE MEEEEEE!!!!

Now you've probably seen these people somewhere. In your moms atic, at the grocery store.

Now incase your an idiot and you didn't get the first definition that I got I copied the actual definition from Urban dictionary.
"A negative term directed to anyone overly obsessed with Japanese culture to the point where they become annoying.Used frequently on the image boards of 4chan.

Most weaboos are uneducated about their obsession of choice and are often noobs who are overly zealous, trying to impress others with their otaku knowledge. Another trait of a weaboo is their desire to "be Japanese".

While the two terms are often fused together, weaboos are very different from anime fans or enthusiasts. A fan may be just as enthusiastic and knowlegable
about Japanese culture, mainly anime, but they neither boast about their knowledge nor call themselves otaku(because of its known negative connatation).

Weaboo: Liek OMG, did anyone see the Inuyasha Movie 3 on teh the Cartoons Network last night! LOLZ Sesshomaru is SO HOTT!!!

Weaboo 2:I hope the Naruto fillers end soon LOL

Humble anime fan: STFU weaboos "

Weaboos are racist pigs who think they're fucking Japanese because they watch anime.
Like, no one gives a shit about your katana collection!
And if you still think you haven't seen these people? Your wrong.
Here's another example.

Weaboo 1: OMG WHAT TE HELL IS WRONG WITH U??? AMERICA AND ENGLAND BELONG TOGETHER!!! USUK IS CONFIRMED!!!

Weaboo 2: YOU DON'T SHIP WHAT I DO AND LIKE THE ANIME I LIKE, SO I'M GOING TO HARASS YOU.

Now have you seen these people?
